I would probably bet against the EVO over what you have combined.
I'm absolutely floored by how good the Azur line is.
I have the Gustard X26 Pro DAC -> 851a -> 851w -> KEF LS50 Meta's and KUBE 12b
I thought getting a dedicated preamp would be a step up, boy am I wrong so far.
I just got the Rotel 1590MK2 ($2100 USD) thinking a dedicated preamp with XLR outs to my amp would be a sound improvement from the Azur 851a ($1500 USD) and unbalanced outs to my Azur 851w.
I'm shocked how good the 851a sounds over the Rotel, like incredibly surprised how dynamic, wide and colored the Azur 851a is over the dedicated higher priced Rotel. It's not even close so far. I'm gonna try unbalanced connections and see if that will do anything, but I can't say enough about the 851a (would assume the same for the 851n).
The Azur line of products are stellar in my opinion and I'm doubtful you'll find the EVO will give you what you already have. I'm gonna give this Rotel maybe another two weeks then I'm gonna send it back, but you can always give the EVO a try.
